first I'm not sure that pjsip can transmit mp3 format sound file, second you should spend some time learning this function pjsua_conf_connect() including some functions around it and learning things from this pagehttp://trac.pjsip.org/repos/wiki/media-flow ------------------ Original ------------------ From: "neili ma"<neilimaye@xxxxxxxxx>; Date: Tue, Jul 5, 2011 08:21 PM To: "pjsip"<pjsip at lists.pjsip.org>; Subject: Simple_pjsua Hello pjsip list, I'm doing my master thesis with pjsip open source 1.10v and I never used it before. I'm writting to ask for help with the sample ''simple_pjsua''. I am trying to send a MP3 media from my desktop to my laptop. I found in internet that the code I have to add is like this: pj_status_t stream_to_call( pjsua_call_id call_id ) { pjsua_player_id player_id; status = pjsua_player_create("media.mp3", 0, NULL, &player_id); if (status != PJ_SUCCESS) return status; status = pjsua_conf_connect( pjsua_player_get_conf_port(), pjsua_call_get_conf_port() ); } but I don't know where and which additional changes I have to make. Can someone lent me a hand? Thanks in advance -------------- next part -------------- An HTML attachment was scrubbed...
